Charge 3 miles

[Pa4]

A friend of mine and myself just took a long walk.  we both have charge 3 fitbits and set it at the same time to a Walk exercise and hers shows 4.83 miles and mine shows 3.12. We both have it set to our non-dominant hand and it’s tight on our wrist. How can that be?

Hello @Pa4 first question would be which if either is correct?

Have you both calculated and set your stide?

What is the true distance of the walk?

Where you both using gps and see a map of your walk? Is the map accurate?

Thanks

Hi

thanks for your help.

Do you know how we calculate/set our stride?

We were both using the GPS/ walk setting via exercise. I never get a map anymore but my friend does.  I heard preciously that I need a new phone to show the map because my OS can’t be updated on my old phone.   I have an iPhone 6 and she does not have IPhone.  

Any ideas?
